+###Thrift version conflicts
+Jaeger client uses `org.apache.thrift:libthrift:0.9.2`. If your project depends on a different
+version of `libthrift`, it is recommended that you use the shaded `jaeger-thrift` jar we publish
+which packages it's own `libthrift`.
+
+To depend on the shaded jar, add the following to your maven build.
+Note that this is only supported for a jaeger version >= 0.15.0
